Chapter 23: Problem 4

A lab technician is looking for a slide that shows an example of permanent tissue. Which slide is the best choice? a. a slide of the apical bud of a stem b. a slide obtained from the intercalary meristems c. lateral meristem in the vascular cambium d. secondary xylem

Short Answer

Expert verified
d. secondary xylem

Step by step solution

01

Identify Permanent Tissue

Permanent tissue consists of cells that have ceased to divide and have completed their growth. Examples include xylem, phloem, and epidermis.
02

Analyze the Given Options

Evaluate each option to determine if it fits the characteristics of permanent tissue.
03

Evaluate Option A

Option A: The apical bud of a stem contains apical meristem, which is involved in the division and growth of cells. This is not permanent tissue.
04

Evaluate Option B

Option B: Intercalary meristems are responsible for the growth at the base of leaves or internodes. This indicates ongoing cell division, so it is not permanent tissue.
05

Evaluate Option C

Option C: Lateral meristem in the vascular cambium is involved in the growth processes such as increasing the thickness of stems and roots. This is a type of meristematic tissue, not permanent.
06

Evaluate Option D

Option D: Secondary xylem is composed of cells that are no longer dividing and are fully differentiated. This is an example of permanent tissue.
07

Conclusion

Based on the explanations, the correct answer is option D, secondary xylem.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

secondary xylem
Secondary xylem is a type of permanent tissue found in plants. It is responsible for transporting water and minerals from the roots to the rest of the plant. Unlike cells in meristematic tissues, cells in secondary xylem are no longer dividing. They have fully differentiated and matured. This makes secondary xylem a perfect example of permanent tissue. You can observe secondary xylem in woody plants, where it forms rings, commonly known as growth rings. These rings are crucial indicators of a tree's age. Each ring represents one year of growth and consists largely of secondary xylem formed during that year.
meristematic tissue
Meristematic tissues are the regions in a plant where rapid cell division takes place. Unlike permanent tissues, the cells in meristematic tissues are young and continuously dividing. There are three main types of meristematic tissues:
  • Apical Meristems: Found at the tips of roots and shoots, promoting vertical growth.
  • Intercalary Meristems: Located at the base of leaves or stems, helping in elongation.
  • Lateral Meristems: Found in the vascular cambium and cork cambium, aiding in girth or thickness growth.
Because of their role in growth and regeneration, meristematic tissues are not considered permanent tissues.
plant cell differentiation
Plant cell differentiation is the process by which unspecialized cells become specialized to perform distinct functions. This process is crucial for the development of various plant organs and tissues. In the context of permanent tissues, once a cell undergoes differentiation, it ceases to divide and takes on a specialized role. For instance, cells in the secondary xylem become specialized to form thick walls that aid in the transport of water and nutrients. Differentiation is a vital part of plant growth and development, ensuring that plants have the appropriate structures to sustain life and perform specific tasks, like photosynthesis or nutrient transport.

An herbicide causes roots to shrivel and die. What is the most direct consequence for a plant treated with the herbicide? a. The plant will grow normally but will not bloom. b. The plant will dry out because water is not reaching all its organs. c. New leaves will form to compensate for the dying of roots d. The plant will grow normally but will not produce fruit

An herbicide is developed that impairs the function of the cork cambium in woody plants. Which changes in the plant should be monitored to gauge the effectiveness of the herbicide? a. Cork will not be produced and the plant will not increase in girth. b. Excess cork will be produced and annual rings will not be formed. c. Cork will not be produced and the plant will not be able to exchange gases. d. Excess cork will be produced and the plant will not increase in girth.

Besides the age of a tree, what additional information can annual rings reveal? a. Annual rings can also indicate the height of the tree. b. Annual rings can also indicate the climatic conditions that prevailed during each growing season. c. Annual rings can also indicate in which season the tree was sown. d. Annual rings can also give an estimation of how long a particular tree is going to live.

A plant biologist is examining sections of plant tissue under the microscope. The slides are not labeled and the biologist is interested in simple tissues. Which of the following slides is a sample of a simple tissue? a. cells dividing rapidly in a stem b. root cambium showing different types of cells c. parenchyma showing only one type of cell d. leaf displaying the vascular bundle where diverse types of cells are involved in transport
